Evaluating Field Techniques for Collecting Effluent Samples for Trace Metals Analysis
Section 1
Introduction
The Clean Water Act requires that ambient water quality criteria (WQC) published by EPA reflect the
latest scientific knowledge concerning the physical fate (e.g., concentration and dispersal) of pollutants, the
effect of pollutants on ecological and human health and welfare, and the effect of pollutants on biological
community diversity, productivity, and stability. Although the Clean Water Act does not require EPA to
consider analytical capability when setting WQC levels, the identification of methods capable of measuring
pollutants at WQC levels is an obvious goal.
In 1992, EPA promulgated numeric criteria for 14 states at 40 CFR Part 131.1 This regulation, known as
the National Toxics Rule, included numeric WQC for 13 metals. The criteria for some of these metals
require measurement capabilities at levels as much as 280 times lower than those achievable using
conventional EPA methods. One of the greatest difficulties associated with making reliable measurements
of trace metals at WQC levels concerns the ability to preclude contamination during sample collection,
handling, and shipment.
As part of EPA's effort to implement the use of metals criteria in National Pollutant Discharge Elimination
System (NPDES) permits, the Office of Science and Technology's (OST) Engineering and Analysis
Division (EAD) was charged with developing protocols for sampling trace metals at EPA WQC levels. In
response to this charge, EAD developed a two tiered approach that focused, first, on the collection of
ambient water samples and second on the collection of effluent samples. The first phase of this approach
was addressed with the development of a draft March 1994 document titled, Method 1669: Sampling
Ambient Water for Determination of Trace Elements at EPA Water Quality Criteria Levels. This March
1994 draft was distributed for limited peer review, and comments and suggestions were incorporated into a
revised draft released in December 1994. Method 1669 was revised again in April 1995 to reflect
comments by states and EPA Regions and to include field preservation procedures for trivalent and
hexavalent chromium. It was further revised in January 1996 to reflect the WQC levels published in a May
4, 1995 interim final rule.
With the completion of Method 1669, EAD began focusing on the development of effluent sampling
procedures, with two primary objectives: (1) developing procedures capable of producing uncontaminated,
representative samples, and (2) developing procedures that would be cost-effective and reasonably easy to
use. Because many permits require the collection of composite samples for trace metals, and because the
use of automated compositing devices can be less labor-intensive than collection of multiple grab samples,
a primary goal was to identify and demonstrate the applicability of automated compositing devices and
techniques. EAD met with several organizations to discuss and observe a variety of techniques being used
to collect and handle wastewater samples for low-level metals monitoring. Based on its discussions with
these organizations, EAD devised an automated effluent compositing system composed of commercially
available parts. The system was designed to be both cost-effective and easy to implement.

referred to as "The National Toxics Rule"), 40 CFR Part 131, (57 FR 60848, December 22, 1992).

Evaluating Field Techniques for Collection of Effluent Samples for Trace Metals Analysis	
This report presents the results of an EAD study designed to evaluate its automated sampling device and to
test manual effluent sampling and compositing techniques. Another purpose of this study was to evaluate
various sample handling techniques in order to determine the level of cleanliness that is most appropriate
for effluent sampling. For the purposes of this study, Method 1669 was adapted to allow for sampling of
effluent samples. EAD previously implemented these adaptations in its 1994 study of nine publicly owned
treatment works (POTWs) in the Great Lakes basin.2

Section 2
Study Objectives
The objectives of this study were to:
(1)	Determine if EAD's automated compositing device is capable of collecting clean blanks and
uncontaminated field samples.
(2)	Compare results of composite samples collected with the automated sampling device to manual and
mathematical composites of effluent grab samples collected with Method 1669 clean protocols.
(3)	Compare the analytical results associated with EAD's composite samples against results from
composite samples collected by the site personnel using the site's sampling protocols.
(4)	Evaluate the ease of using EAD's automated compositing device and identify improvements that
may simplify field procedures.
(5)	Determine if clean blanks and uncontaminated effluent samples can be obtained using gloves-only
clean protocols described in Method 1669 (i.e., without windsuits for protection of samples from
atmospheric sources of metals).
In addition to the overall objectives described above, EAD identified three data quality objectives for the
study. First, the data gathered must have included sufficient quality control (QC) results to demonstrate
that contamination had not occurred. Contamination was defined in this study as the presence of a
pollutant in blank samples at a concentration that was more than one-tenth the lowest WQC. Second, grab
samples collected during the study must have been handled in accordance with clean protocols described in
Method 1669, unless deviations were determined to have been necessary by field personnel involved in the
study. Such deviations were to be clearly documented so that EAD could use results from the study to
develop written effluent grab sampling protocols, and if appropriate, modify Method 1669. Finally,
automated procedures for collecting and compositing samples must have been documented by the field team
so that EAD could use results from the study to develop written protocols for collecting automated
composite samples.

Study Design and Implementation
The study described in this document was managed by EAD's Analytical Methods Staff (AMS). Day-to-
day management and coordination of study activities was provided by the contractor-operated Sample
Control Center (SCC) under AMS guidance. SCC coordinated laboratory analysis, received and validated
all analytical data, and performed statistical analyses. AMS drew conclusions from the results and is using
these results to draft a method for collecting effluent samples.
With few exceptions, the study was implemented as described in the Study Plan for Evaluating Field
Techniques for Collection and Handling Effluent Samples for Trace Metals Analysis (December 1996).
Procedures followed during the study are summarized below.
3.1 Summary of Study Design
Two POTW sites were sampled using five techniques:
(1)	EAD's automated sampling system programmed to collect composite samples over a 24-hour
period ("24-hour composites")
(2)	EAD's automated sampling system programmed to collect composite samples over a working shift
("shift composites")
(3)	Modified Method 1669 clean protocols with full protective clothing for collection of effluent grabs
("full suit grabs")
(4)	Modified Method 1669 clean protocols with protective gloves only for collection of effluent grabs
("gloves only grabs"), and
(5)	The automated sampling system used by the facility ("facility 24-hour composites").
Three types of samples were collected with these five techniques: automated 24-hour composites
(techniques 1 and 5), automated shift composites (technique 2), and grabs (techniques 3 and 4).
Grab samples were collected throughout each working shift and analyzed individually; a mathematical
average of the individual results was used to determine a mathematical composite for direct comparison to
the shift composite. Manual composites of individual grab samples also were prepared and analyzed in the
lab for direct comparison to the shift composite. The collection of shift composites and associated grabs
was designed to minimize the need for multiple shifts of sampling personnel during the study. Results of
EAD's 24 hour composites were compared against results from the corresponding facility 24-hour
composites.
Aliquots collected for dissolved metals were filtered in the field using a 0.45 micron capsule filter. To
minimize sample handling, in-line filtration was used to collect grab samples. Due to technical difficulties
with adapting in-line filtration procedures to automated compositing devices, however, the dissolved metals
fraction of all automated composite samples were filtered after sample collection in accordance with the
post-filtration procedures outlined in Method 1669.

Evaluating Field Techniques for Collecting Effluent Samples for Trace Metals Analysis
Samples were analyzed by Method 1631 for total and dissolved concentrations of mercury, by Method
1632 for total and dissolved concentrations of arsenic, and by Method 1638 for total and dissolved
concentrations of antimony, cadmium, chromium, copper, lead, nickel, selenium, silver, thallium, and zinc.
3.2	Equipment Cleaning and Preparation
In accordance with Method 1669, equipment and container materials were chosen based on the metals of
interest. Samples to be analyzed for mercury were collected in fluoropolymer (FEP) containers, and the
samples to be analyzed for the other metals were collected in polyethylene containers. Prior to sampling,
all tubing components, connectors, and sample containers were cleaned and processed in the laboratory, as
described in Method 1669, and double bagged for storage and transport to the field. The cleaning facility
utilized the guidance stated in the associated trace metals methods to thoroughly clean, store, and ship all
required equipment. In general, this involves the use of hot acid baths and copious rinsing with reagent
water.
3.3	Automated Composite Sampling System
The automated composite sampling system used in this study consisted of a commercially available,
automatic sampling unit outfitted with pre-cleaned tubing and sample containers. The automatic sampling
unit housed a peristaltic pump and a programmable, electronic controller and included FEP tubing (3/8 "
ID x 7/16 " OD) for suction and discharge lines, styrene/ethylene/butylene/silicone (SEBS) pump tubing
(CFLEX, 3/8 "ID x 5/8 " OD), and polyethylene or FEP composite containers. This system could be
programmed to collect time- or flow-proportioned composites, and could be used to collect both effluent
and blank samples.
The automated effluent compositing system used in this study is only one example of an automated device
that could be developed for effluent sampling. EAD did not attempt to evaluate all potential components or
automated equipment to identify the best alternative. Instead, EAD focused on demonstrating that an
automated system could be assembled using commercially available parts in a cost-effective manner to
obtain clean field blanks and uncontaminated samples.
Figure 1-A presents a schematic diagram of the apparatus as used to collect composite effluent samples. In
this system, suction tubing was placed into the effluent stream and supported with PVC piping. A
minimum length of SEBS tubing was placed in the peristaltic pump head and attached to the suction line
and the discharge line connected to the composite container. Polyethylene carboys (15L) were used as
composite containers. These carboys were fitted with caps that had two ports, with FEP fittings, for
attachment of an inlet line and a vent filter to minimize atmospheric exposure to the sample. FEP bags
(30L) were used inside the composite containers when collecting samples for mercury analysis.
Field filtered samples were obtained from composite containers immediately following the collection period
using clean sampling techniques and capsule filters as described in Section 8.3 of Method 1669 (Figure 1-
B).

Evaluating Field Techniques for Collecting Effluent Samples for Trace Metals Analysis
3.4 Sample Collection Techniques
All field collection procedures were thoroughly documented in a field log and in detailed field notes. These
notes described field conditions, problems encountered during sample collection, resolutions taken to
correct these problems, and field crew comments regarding the clarity and ease of use of the field
techniques tested in this study. The field procedures followed during this study are summarized below in
Sections 3.4.1 - 3.4.3.
3.4.1	Automated 24-hour Composite Sampling
To compare results from EAD's automated compositing device with those produced by the facility's
automated compositing device currently in use, EAD programmed four of its automated devices to collect
and composite aliquots over a single 24-hour period at each site. This period was concurrent with the 24-
hour period sampled by the POTW. The POTWs that were sampled used an automated 24-hour composite
system based on a peristaltic pump design. Tubing and other sampling equipment were not pre-cleaned,
however, pre-cleaned sample bottles were provided to the POTWs by EAD for sample collection and
transport. It should be noted that the Site 1 POTW used a flow-proportioned automated compositing
device, whereas EAD's devices and the Site 2 POTW device were designed to collect composites based on
pre-defined time intervals. One of the EAD devices was used to collect effluent samples for total mercury
analysis and another was used to collect blank samples for total mercury analyses; both of these devices
included FEP equipment. The other two devices were used to collect effluent and blank samples for all
other total recoverable metals and included polyethylene equipment. A split from each EAD and the
POTW 24-hour compositing device was analyzed by the POTW laboratory and by EAD's contract
laboratory.
3.4.2	Automated Shift Composite Sampling
EAD programmed its four remaining automated sampling devices to collect and composite aliquots at the
four sampling times in which the grab samples were collected at each site. Grab samples were collected at
four discrete time intervals per day on three separate sampling days at each site. Therefore, EAD collected
automated shift composites on each of these days, concurrent with each of the sampling periods during
which grab samples were collected. Deviations from this approach are noted below in Section 3.7.
Two of the four sampling devices were fitted with FEP bag assemblies and deployed for mercury (a blank
sampling device and an effluent sampling device) and two were deployed with polyethylene containers for
the remaining metals (also a blank sampling device and an effluent sampling device).
3.4.3	Manual Grab Sampling
Grab samples were collected by staff at four discrete time intervals per day over a three day period at each
POTW site. In most cases, each grab sample was collected concurrently by staff wearing full protective
clothing and by staff wearing protective gloves only. Deviations from this approach are noted in Section
3.7.

-------
Evaluating Field Techniques for Collection of Effluent Samples for Trace Metals Analysis
Each grab was collected as a dissolved (filtered) aliquot and analyzed for all twelve metals listed in Section
2.3. Duplicate samples were collected and analyzed for one of four time intervals on one of the three
sampling days. To minimize analytical costs of the study, unfiltered manual grab samples (i.e., grab
samples for total recoverable metals) were not collected.
Grab sample aliquots and blanks were shipped to the laboratory for analysis of individual grabs and
manual compositing of individual grab samples. Laboratory compositing procedures are described in
Section 3.5.
3.5	Manual and Mathematical Composites
Following receipt of grab samples, the laboratory prepared and analyzed (1) each of the individual grab
samples, and (2) manual composites of each set of four grab samples collected during each shift. Results
of the individual grab sample analyses were mathematically averaged to provide a mathematical composite
result that could be compared with results of the manual composite and with results of the automated shift
composites.
Manual composites of the individual grab samples were prepared in the laboratory. Each of the four
parent-grab samples was shaken vigorously and an aliquot (25 |aL for Hg and 2.5 mL for other metals) was
removed for compositing. The laboratory strictly adhered to clean protocols during all sample handling
procedures to minimize the potential for contamination during the manual compositing process.
Composites of manually and mathematically composited grab blanks were prepared and analyzed to
evaluate the impact of contamination, if any.
3.6	Sample Shipment, Laboratory Processing, and Analysis
Each day after samples were collected and filtered, samples were shipped to the lab via overnight courier,
as described in the study plan and in Method 1669, with one exception noted below in Section 3.7. Upon
receipt, the laboratories preserved the samples in accordance with the associated method requirements for
analysis. Samples were analyzed for total and dissolved concentrations of the following metals with the
referenced methods:
•	Arsenic-EPA Method 1632: Inorganic Arsenic in Water by Hydride Generation Quartz Furnace
Atomic Absorption, July 1996, EPA 821-R-96-013.
•	Mercury-EPA Method 1631: Mercury in Water by Oxidation, Purge and Trap, and Cold Vapor
Atomic Fluorescence Spectrometry, July 1996, EPA 821-R-96-012.
•	Antimony, cadmium, chromium, copper, lead, nickel, selenium, silver, thallium, and zinc-EPA
Method 1638: Determination of Trace Elements in Ambient Waters by Inductively Coupled
Plasma-Mass Spectrometry, January 1996, EPA 821-R-96-005.
The POTW laboratory analyzed zinc by inductively coupled plasma spectrometry, mercury by cold vapor
atomic absorption, and all other metals by graphite furnace atomic absorption. The detection limits for
these analyses did not meet the requirements for the objectives in this study, therefore, the data is not
presented in this report. The data is available upon request3.

Evaluating Field Techniques for Collecting Effluent Samples for Trace Metals Analysis
3.7 Deviations from the Study Plan
As was noted in the study plan, the primary purpose of sampling at Site 1 was to test the equipment and
determine if additional resources were needed to fully implement the study at Site 2. To the extent feasible,
the study would be implemented as designed at Site 1, but on-site changes were to be expected in order to
accommodate unforeseen logistical problems without increasing study costs or time in the field. In keeping
with this strategy a few deviations were made. These and other minor deviations are as follows.
•	The pre-cleaned sample bottles were not filled with reagent water prior to transport to the field. It
was anticipated that contamination was unlikely to occur in the extremely short time between
cleaning and use in the field and that the addition of water to each bottle would, therefore, increase
shipping costs unnecessarily. In the unlikely event that contamination was widely detected in blank
samples, comparison of field blanks with laboratory equipment blanks would provide an
opportunity to determine if this deviation compromised study results.
•	Because of logistical problems in the field, including a limited volume of blank reagent water, the
Day 2 (Site 1) shift, consisting of four grab samples and associated composite sampling, was split
into two days of sampling on 12/4/96 and 12/5/96. Two grabs and associated composites were
collected on 12/4/96 and the other two grabs and associated composites were collected on 12/5/96.
(Tables A-6 and A-8 in Appendix A provide additional details and a key to the manual and
mathematical compositing of grab samples collected on each day of sampling).
•	Due to the Day 2 shortage of reagent water, the automated shift composite blank for mercury also
was not collected on this day at Site 1.
•	Due to time constraints, the automated shift composites collected on Day 1 at Site 2 were stored at
room temperature and filtered 24 hours after sample collection. In addition, several samples were
collected under windy and rainy conditions during Day 1 at Site 2.
•	Although the original study design specified that many of the blank samples collected were to be
held and analyzed only if other blanks showed signs of contamination, most of the blanks collected
from the first site were analyzed. This change was made because some cost savings had been
achieved through modifications described above and to provide additional information for the
second sampling event.
•	Conversely, blank results obtained from the subset of samples analyzed from the second sampling
event were not evaluated in time to allow for analysis of additional blanks when indicated by
contamination in the blanks that were analyzed. Appendix A provides results for all of the field
and blank samples that were ultimately analyzed in this study

Section 4
Data Reporting and Validation
All analytical results were submitted to SCC for review and validation. Separate reports were submitted
for each week of sampling. The laboratory submitted both summary level and raw data in hardcopy format
and provided summary data in electronic format. Raw data included copies of worksheets, and laboratory
notebooks showing tare and sample weights, sample volumes, solvent volumes, and other data that allow
the final results to be traced to the analytical steps performed.
SCC reviewed the data in accordance with the specifications listed in EPA Methods 1631, 1632 and 1638,
EPA's Guidelines for the Documentation, and Evaluation of Trace Metals Data Collected for Clean
Water Act Compliance Monitoring (July 1996, EPA 821-B-96-004), and objectives described the Study
Plan for Evaluating Field Techniques for Collecting and Handling Effluent Samples for Trace Metals
(December 1996). Problems identified during SCC's data review were discussed with the laboratory for
resolution. If possible and appropriate, sample re-analysis, re-calculation, or data resubmission was
requested to correct deficiencies and maximize the amount of usable data gathered in the study. With the
qualifications described below, all data were considered to be acceptable for use in this study.
For the purpose of reviewing data against study objectives, contamination was defined as any blank sample
that showed a positive result greater than or equal to 1/10 the lowest EPA water quality criterion for that
pollutant. Because many MDLs were below this value, it was possible for blank samples to exceed the
MDL without compromising study objectives.
To further assess the effects of contamination, blank results that exceeded either the MDL or 1/10 the
lowest EPA water quality criterion were compared against corresponding field samples results. In most
cases, the field sample results were more than 10 times higher than the corresponding blank sample results,
indicating that the blank concentrations had no adverse impact on data quality. In some cases, field sample
results were between 5 and 10 times higher than the corresponding blank sample values, indicating that the
field sample results might be biased by contamination. EPA and SCC data users were cautioned to
consider these field sample results as maximum values when evaluating the data. In a few cases, the field
sample results were less than five times the value reported in the corresponding blank. In such cases, data
users were cautioned that there is no way to ascertain whether the presence of the analyte in the field
sample was due to contamination. Because one purpose of this study was to characterize differences
between techniques, including differences attributable to blank contamination, field sample results that were
similar to blank sample concentrations were not considered to pose a significant problem.
Other data quality issues of note included the following:
(1)	The percent recovery of lead in the MSD aliquot of sample 35524 exceeded the Method 1638
specification for MS/MSD spike recovery. The RPD between the matrix spike (MS) and the MSD
analyses also exceeded the corresponding method specification. Based on these information, data
for this sample were provisionally included for use in evaluating study results, but data users were
cautioned about the potential for bias with this data point.
(2)	The concentration of mercury in sample 34094 exceeded the top standard of the calibration curve.
The sample was not reanalyzed at dilution. Therefore, the result for this sample was qualified as
10
June 1998

-------
Evaluating Field Techniques for Collecting Effluent Samples for Trace Metals Analysis
greater than the reported concentration.
(3)	The laboratory reported a method detection limit (MDL) of 0.6 ng/L for mercury by Method 1631.
This exceeded both the MDL (0.2 ng/L) and the minimum level (0.5 ng/L) required by the method.
At the time of this study, the lowest ambient water quality criterion (WQC) promulgated by EPA
was 12 ng/L. The laboratory MDL of 0.6 ng/L was less than one-tenth the lowest WQC;
therefore, data users were informed that, although the method-specified MDL and MLs were not
obtained for mercury, the elevated MDL that was achieved by the laboratory did not compromise
the sample results or study objectives.
(4)	The blanks for arsenic could not be categorized as "clean" because the laboratory MDL of 0.022
Hg/L exceeded study objectives (the lowest EPA WQC for arsenic is 0.018 ng/L; therefore, the
laboratory's MDL should have been equal to or less than 0.0018 ng/L). Because the arsenic MDL
did not allow assessment of the ability to produce clean blanks at the levels of interest, arsenic
results from blank analyses were removed from further consideration.

Section 5
Results and Discussion
The results presented in this section are organized against each of the five study objectives described in
Section 2.
Results of blank samples collected with the EAD automated compositing device are presented in
Section 5.1. These data can be used to determine if EAD's automated compositing device is
capable of collecting clean blanks (Objective 1). For comparison purposes, manually composited
grab blank results also are presented in this section.
Results of effluent composite samples are presented in Section 5.2. These data allow comparison
of composite results obtained with EAD's automated compositing device against manual and
mathematical composite results obtained from grab samples (Objective 2). These results also
allow comparison of EAD's automated compositing procedure against the automated compositing
procedures used by the POTWs that were sampled (Objective 3).
Field notes, problems and other results that provide information necessary to evaluate the ease of
field procedures used in the study are provided in Section 5.3 (Objective 4).
Results from effluent grab samples collected with protective gloves only and with full protective
suits are summarized in Section 5.4 to allow assessment of whether use of full suits is needed for
low-level effluent sampling of metals (Objective 5).
A complete list of results is presented in Appendix A and highlighted and discussed in this section of the
report. For clarity, detailed information regarding each sample is provided in the Appendix A tables in
order to link individual sample results to results presented in the graphs.
5.1 Blank Samples
Blank results were categorized as either "clean" or "contaminated" for each analyte, depending on whether
the concentration reported in the sample was below or above a level corresponding to one-tenth the lowest
EPA water quality criterion for that analyte.
As was noted in Section 4, none of the blanks for arsenic could be categorized as "clean" because the
laboratory MDL of 0.022 (jg/L exceeded study objectives. Because the arsenic MDL did not allow
assessment of the ability to produce clean blanks at the levels of interest, arsenic results from blank
analyses were removed from further consideration and are not presented or discussed in this report.
A complete list of all other composite blank results is provided in Appendix A, Tables A-l through A-5.
Of the 477 blank results reported during this study, only 20 were categorized as "contaminated" and nearly
all of these were contaminated at levels only slightly higher than the study objective of 1/10 the lowest
WQC. Details regarding these 20 contaminated blanks are provided in Table 5-1. Additional discussion
regarding blank results is provided below.

Evaluating Field Techniques for Collection of Effluent Samples for Trace Metals Analysis
5.1.1	24-hour Composite Blanks
The 24-hour composite sampler proved to be capable of collecting clean field blanks for most of the
analytes that were measured. Several field blanks, however, showed elevated levels of one metal or another
above the corresponding "clean" criterion. For example, no mercury contamination was observed above
the "clean" criterion in any of the 24-hour composite blanks, a small amount of silver contamination was
observed in the first two 24-hour composite blanks collected at the first POTW site, and zinc contamination
was observed in the last 24-hour composite blank collected at the second POTW (Figures 2a-2c).
All six of the 24-hour blank samples were clean for eight of the eleven total recoverable metals analyzed in
the blanks: cadmium, chromium, mercury, lead, nickel, selenium, and thallium (Figure 2d). Although some
blanks were contaminated with silver (2 of 6), selenium (3 of 6) or zinc (1 of 6), no single blank was
contaminated with more than one metal. Appendix A, Table A-l provides a complete list of the 24-hour
composite blank results produced in this study.
5.1.2	Shift Composite Blanks
As with the automated 24-hour compositor, the automated shift composite sampler was capable of
collecting clean blanks for most metals, but sporadic contamination was observed in a few instances.
Because the shift composite samples were analyzed for both total recoverable and dissolved metals, a
comparison can be made between the filtered and unfiltered samples.
Although it might be argued that increased sample handling procedures associated with the filtration
process could lead to increased contamination, results from this study do not support that concern. For two
analytes, it appears that contamination observed in the total recoverable (unfiltered) form of an analyte was
slightly higher than contamination observed in the dissolved (filtered) form of the same analyte in the same
composite blank. For example, one of the composite blanks was contaminated with total recoverable
mercury at a concentration just above the "clean" criterion of 0.0012 pg/L. Although mercury was
detected in the dissolved fraction of the same composite sample, the dissolved mercury concentration was
below the "clean" criterion established for the study (Figures 3a and 3b). Similarly, total recoverable silver
was measured above the "clean" criterion of 0.032 (jg/L in one of the composite blanks and detected at
levels below this criterion in two other blanks. However, dissolved forms of silver were not detected in any
of the corresponding composite blanks (Figures 3c and 3d). The only exception to this trend was for
selenium. In this case, contamination occurred in a dissolved metal field blank but did not occur in the
associated total recoverable blank. Because only one dissolved metal field blank showed elevated levels of
selenium, it is likely that the contamination observed was a random artifact of the overall sampling process
rather than a systematic source introduced from the filtration step.
All four of the automated shift composite blanks were clean at the levels of interest (1/10 WQC levels) for
9 of the 11 total recoverable metals analyzed (mercury and silver contamination occurred in one blank
each) and for 10 of the 11 dissolved metals analyzed (selenium contamination occurred in one blank).
Although some of the blanks were contaminated with silver, mercury, or selenium, no single blank was
contaminated by more than one metal (Figures 4a and 4b). Tables A-2 and A-3 of Appendix A list all total
recoverable and dissolved metal concentrations measured in shift composite blanks from this study.

5.1.3 Manually Composited Grab Blanks
A complete list of manually composited blank sample results is presented in Appendix A, Table A-4 and
summarized in Table 5-2 of this section. Table 5-2 compares results of manually composited blanks to
blank results from EAD's automated 24-hour compositor and EAD's automated shift compositor. As can
be seen in Table 5-2, the manually composited blank samples appeared to be contaminated with a wider
variety of metals than did either of the automatically composited blanks. This suggests that the manual
compositing procedure may be more prone to contamination (presumably from increased sample handling)
than the automated procedures. For example, Sample 34062 (Sample 1, Site 1) was contaminated for three
metals (copper, lead and zinc), and Sample 34084 (Sample 1, Site 1) was contaminated with mercury. All
of the parent individual grab blanks used to create these two manual composites were clean for copper,
mercury, lead, and zinc indicating that contamination may have occurred in the laboratory during manual
compositing (Appendix A, Table A-4). Another trend of interest that can be seen from Table 5-2 is that
one metal (selenium) appeared as a contaminant in at least one blank from each of the three sampling types.

5.2 Effluent Samples
A complete list of effluent sample results is provided in Appendix A, Tables A6 through A9. Highlights of
these results, as they relate to Study Objectives 2 and 3 are discussed below.
5.2.1 Automated Shift Composites compared to Mathematical Grab Composites
Table 5-3 lists the minimum, maximum and mean RPD between each analyte concentration reported in the
automated shift composites and in the associated mathematically composited effluent grabs. Figures 5a-5c
summarize differences between the compositing techniques for each day and site (Days 1, 2, and 3
represent Site 1, and Days 4, 5, and 6 represent Site 2).
Results between the two compositing techniques agreed for the majority of metals analyzed, but were
disparate for several metals, and the variability that was observed with those metals appeared to be
independent of site. For example, a maximum RPD of 8% was observed for copper measurements made
by the two different compositing procedures, but the RPD between pairs of mercury composite samples
ranged from 3% to 97%, with a mean RPD of 47% (Figures 5a and 5b).
Although results for selenium did not agree (the RPD ranged from 5% to 97%, with a mean of 40%), none
of the effluent concentrations reported were above the selenium WQC of 5 (jg/L (Figure 5c). If levels of
selenium seen in the two effluents sampled are typical of most selenium discharges, then it is possible that
the lack of agreement observed in this study is not significant in real world compliance monitoring
situations.

Table A-6 of Appendix A lists all dissolved metal concentrations measured in the effluent samples collected
using the automated shift composite, manual composite, and mathematical grab composite techniques from
this study. The relationship between mathematical and automated compositing techniques is summarized in
Figure 5d. Seven of the 12 metals (arsenic, cadmium, copper, nickel, lead, antimony, and thallium) had
maximum RPD's below 20%. Although a maximum zinc RPD of 46% occurred on one day of sampling,
all other zinc RPDs were less than 20%, and the mean RPD for zinc was 10%, suggesting fairly good
agreement among the sampling techniques for this metal.
5.2.2 Mathematical Grab Composites Compared to Manual Grab Composites
Trends between mathematically composited grab samples and manually composited grab samples were
similar to trends observed between automated shift composites and mathematical composites. In particular,
manually composited grab results agreed with mathematically composited grab results for the majority of
metals analyzed, but were disparate for several metals (Figures 6a - 6d). For example, RPDs between all
pairs of manually and mathematically composited samples were less 20% for arsenic,

cadmium, copper, nickel, lead, antimony, and zinc, but rather high RPDs were occasionally observed for
silver, chromium, mercury, and selenium. Mean RPDs between manually and mathematically composited
samples were less than 20% for all metals except silver and selenium. Table 5-4 lists the minimum,
maximum and mean RPD between the effluent concentrations in associated samples for each analyte. A
complete list of mathematically and manually composited sample results is provided in Appendix A, Table

5.2.3 EAD 24-hour Composites Compared to Site 24-hour Composites
Table 5-5 and Figures 7a - 7d summarize comparisons between results obtained with the EAD automated
compositor and the automated compositing devices used by the POTWs that were sampled. Although there
was some agreement between results produced by each organization's device, the agreement for some
metals was not as strong as the agreements seen in Sections 5.2.1 and 5.2.2. For example, there was a
strong lack of correlation between copper and mercury results obtained with the EAD and the POTW
compositing devices. A mean RPD of 34% and a maximum RPD of 97% was observed for copper, and a
mean RPD of 70% and a maximum RPD of 193% was observed for mercury when comparing the
automated EAD and facility devices. On the other hand, agreement was reasonably good for some metals.
For zinc, the RPD ranged from 2.8% to 23.7% with a mean RPD of 14.1%; the RPD for cadmium ranged
from 0% to 33%, with a mean RPD of 7%; and the RPD for antimony ranged from 0% to 34%, with a
mean RPD of 7%.

Evaluating Field Techniques for Collection of Effluent Samples for Trace Metals Analysis
5.3	Ease of Using Automated Composite Devices
The level of effort involved in setting up and using the automated composite sampling system in the field
was comparable to that required for any portable sampling unit typically used for effluent monitoring.
However, additional care needed to be taken in handling and assembling the components, in accordance
with the philosophy of contamination control presented in Method 1669. Sampling personnel wore clean,
powder-free, latex gloves during all operations involving handling of the apparatus and containers. As a
precaution for this study, tubing and composite containers were replaced after each sample was collected
with items that had been cleaned and processed in accordance with Method 1669 to prevent cross
contamination. Future studies should evaluate the need for this precaution.
A modification that was made to the system for this study was the use of a separate enclosure to house the
composite container, rather than using the base of the automatic sampling unit. A 28-gallon plastic barrel
and a lid was used for this purpose, and was placed adjacent to the sampling unit, as indicated in Figure la.
This facilitated access to the composite container for observation.
The polyethylene carboys worked well as composite containers, but the large FEP bags were found to be
cumbersome to handle and difficult to clean. Overall the composite sampling system was easy to use in the
field.
5.4	Method 1669 with gloves only
Tables A-10 and A-12 of Appendix A list all dissolved metal concentrations measured in the blank grab
samples collected. Eleven grab blanks were collected wearing full protective suits, and nine grab blanks
were collected wearing only protective gloves. Figures 8a and 8b summarize differences observed between
these techniques for each metal. As can be seen from these figures, nearly all blanks were clean for all the
metals with both techniques. Only sporadic instances of silver, mercury, and selenium contamination were
observed. Although two grab blanks collected wearing full suit protection showed contamination for silver
(1/11) and selenium (1/11), all 11 blanks were clean for nine metals (cadmium, chromium, copper,
mercury, nickel, lead, antimony, thallium, and zinc). Of the nine blanks collected with gloves only, two
were contaminated with selenium and one with mercury (Figures 9a and 9b). In other words, selenium
contamination was observed with both techniques (3 instances of contamination), mercury contamination
was observed only with the gloves only technique (one instance of contamination), and selenium
contamination was observed only with the full suit technique.
In general, good agreement also was observed between the effluent concentrations reported with the gloves
only technique and the full suit technique. Tables 5-6 and Figure 10 summarize relative percent differences
observed between gloves-only effluent grabs and full-suit effluent grabs. As can be seen from this figure, 9
of the 12 metals showed agreement within approximately ± 30%. The exceptions observed were mercury,
selenium, and thallium. Figure 10 also indicates that there appears to be no trend towards a high bias for
samples collected with the gloves-only procedure. This is consistent with the results observed with gloves
only and full suit blank samples.

Evaluating Field Techniques for Collecting Effluent Samples for Trace Metals Analysis
These data suggest that it may not be necessary or advantageous to wear full protective suits when
collecting effluents for the levels of interest in this study. Due to the small sample size and the high degree
of site-specific variability, however, further study in this area may be warranted.

Section 6
Discussion and Conclusions
This study was conducted at two POTW sites. Because contamination sources and levels vary spatially
and temporally, the results produced in this study may not be typical of results for other sites. Given these
constraints, results of this study suggest that automated compositing systems, composed of pre-cleaned,
readily available components, can be used to collect clean blanks and uncontaminated field samples at
WQC levels, and that in most cases, automated compositing systems are more reliable than manual
compositing procedures for trace metals. Study results also indicate that compositing techniques for some
metals such as mercury, silver and zinc may be more problematic than others. Finally, study results
suggest that it may not be necessary or advantageous for facilities to use full suit protection when collecting
effluent samples at water quality based permit limits for metals.
Overall, study results are promising and suggest that reasonably cost-effective procedures can be
implemented for collecting uncontaminated effluent grab and composite samples at water quality based
permit levels. Further study by EPA or by other organizations is likely to yield additional data that
supports these conclusions.
